Hello! We are a supplier of electronic assemblies primarily for the military. We are in the process of switching over from RMA to water soluble flux (Kester 1189A). Typically, rosin flux has a density of .890, which the flux density controllers on automated equipment can easily control. Kester's 1189 flux has a density requirement of 1.2. Standard flux density controllers can only be dialed up to .999, so how do I control the density of the water soluble flux? What modifications must I incorporate in my wave soldering process to automatically monitor and control the new flux type? I would like to hear from those who already use the Kester 1189A flux to see how they monitor and control the density. Jim Marsico AIL Systems, Inc 516-595-5879
